Radiation-dominated Snowmelt on MarsA set of microclimatic conditions conducive to the generation of liquid water is being sought to see whether their requirements are any less stringent than those suggested by the global-climatic models. In particular, the melting of snow and ice in the equatorial zone (where the valley networks are preferentially situated) is investigated with a model that includes detailed infrared radiation transfer between the atmosphere and the snow, penetration of sunlight into the snow, sensible heat transfer to the atmosphere, and water vapor diffusion within the surface boundary layer. IR fluxes are calculated by using pressure and temperature dependent forms for the band absorptances of CO2 and H2O in the spectral range 50 to 2000/cm.
